In reading about TeX's hyphenation algorithm, I found the tex-hyphen repo with a bunch of patterns listed (over 4,000 in that file). The answer on the hyphenation algorithm suggested that they compile and generate these patterns from existing dictionaries from publishers. I imagine these to be, rather than TeX hyphenation patterns, individual hyphenation examples such as exa-mple for "example" or whatever. How the hyphenation points are determined I have no idea, seems like it is on a per-word basis without a clear science (hence the patterns).
So I wanted to see if there exists these dictionaries of the hyphenation examples (as opposed to the hyphenation patterns). Wondering if one could list some resources where they may be found, or if none then knowing they are private or whatever would be helpful.
